Free birth chart calculator
Your whole chart, calculated. Not a summary of it.

Ascendant, all nine grahas, every sign, house, degree and nakshatra. No email, nothing held back for a paid tier.

Without a birth time you still get every planet. The ascendant and houses need it, and we will say so rather than assume noon.

Free birth chart calculator

This calculator builds your D1 chart, the main birth chart of Vedic astrology, from the actual positions of the planets at your moment of birth. It uses the sidereal zodiac, so the placements will usually differ from a Western chart by about one sign.

What the calculator gives you

Why does the time of birth matter so much here?

For a Moon sign the date is usually enough. For a full chart it is not.

The ascendant is the point of the zodiac rising on the eastern horizon, and the Earth's rotation moves it through a full sign roughly every two hours. Since the houses are counted from the ascendant, an error of a few hours moves every planet into a different house and changes the reading entirely.

What is the ascendant?

The lagna is the first house, and in Vedic astrology it is the anchor of the chart. It describes the body, the outward direction of a life, and it fixes where all the other houses fall.

This is one reason Vedic and Western readings diverge in practice as well as in theory: much of Vedic interpretation runs from the lagna, while much of Western interpretation runs from the Sun.

How do I read what the calculator gives me?

The table has five columns, and each answers a different question.

What should I look at first?

Three lines carry most of the weight, and the rest is detail on top of them.

  1. Your ascendant, at the top. It anchors everything else.
  2. Your Moon — its sign is your Janma Rashi and its nakshatra is your birth star. Vedic astrology reads this before the Sun.
  3. Where the ruler of your ascendant sits. We show this on the first line: which planet rules your rising sign, and which sign and house it landed in.

If you want the longer version of this, the guide to reading a birth chart walks through it properly, and the nakshatra guide covers the 27 divisions.

Why is this called a D1 chart?

Vedic astrology uses divisional charts, the vargas, each derived from the main one by subdividing the signs. D1 is the main chart, the rashi chart, and it is what almost everyone means by a birth chart.

The others zoom into particular subjects — D9 for marriage and inner strength, D10 for career — and they are read alongside D1, never instead of it. This calculator returns D1, which is where any reading starts.

What if two planets sit in the same sign?

They are then said to be conjunct, and the tradition reads them as blending: their significations mix, and the stronger placement colours the weaker. Three or more in one sign is a stellium, and it concentrates a large part of the chart into one area of life.

Rahu and Ketu are always exactly opposite each other, six signs apart, so they never share a sign. If your table shows them together, something is wrong and we would want to know about it.

Common questions

Is this birth chart calculator free?

Yes, completely. It returns your full Vedic chart with no email required and nothing held back.

What do I need to calculate my birth chart?

Your date of birth, your place of birth, and your time of birth. Time matters here more than for a Moon sign, because the ascendant changes roughly every two hours and the house positions depend on it.

What if I do not know my birth time?

You will still get every planet's sign, degree and nakshatra. The ascendant and the house positions cannot be determined without a time, and we say so rather than defaulting to noon and presenting it as fact.

Is this a Vedic or Western chart?

Vedic, using the sidereal zodiac with the True Chitra Paksha ayanamsa. Your Western Sun sign is shown alongside for comparison, because for most people the two differ.

How this is calculated

Positions come from the JPL DE421 ephemeris, with the sidereal correction applied using the True Chitra Paksha ayanamsa, and the time zone resolved from your birth coordinates for that date. The full method is on the methodology page.

An honest note

Astrology here is for reflection and self-understanding. It is not prediction, diagnosis or advice, and no outcome is promised. The astronomy is calculated and real; the meanings are a tradition of interpretation.
